Apparently its not derived from a person himself:
….It got its name, according to Richard Huelsenbeck, a German artist living in Zurich, when he and Ball came upon the word in a French-German dictionary. … “Dada is 'yes, yes' in Rumanian, 'rocking horse' and 'hobby horse' in French,”….
Norman! What did you put in my tea?

The spirit of Dada. That's cool. I'm not all that familiar with him. Maybe I will go look up some of his stuff.
"My life is over. I might as well dance with Johnny Slash!"

This was on you tube by the person who uploaded the video:
Images painted directly on the film follow the rhythm of an upbeat keyboard and percussion piece composed by the filmmaker Chel White. 1985
The artform is done in the spirit of Dada according to IMDB, which as google explained, is in the nature of the satirical and nonsensical.

I would have no idea how it was done, but I love the overall effect. It is very trippy.
I have no idea what "Metal Dogs of India" means.
"My life is over. I might as well dance with Johnny Slash!"

It looks like a bit of experimental computer animation and like another poster suggested, scratched in emulsion on raw film stock and perhaps painted or colored lighted projected through it.
It is funky sounding and even quaint, but hardly seems worth the time and effort for something so slight and amateurish.

I'd rather get high on marijuana, but it's interesting

I never thought about that. But I guess that is what it looks like.
"My life is over. I might as well dance with Johnny Slash!"

Made entirely without a camera? Was it just paint directly on film then?

I thought so! Takes me to a different place.
"My life is over. I might as well dance with Johnny Slash!"

Interesting!
MAGA! FAFO! Schrodinger's Cat walks into a bar, and doesn't. Dumbocraps: evil people who celebrate murder.

I was referring to the original clip, not the more meditative one you posted.
Norman! What did you put in my tea?

It was not meant to be a literal representation of the visual and aural, only a representation of
the vibe
of a mellow marijuana experience.
I still await a response from hutch about present day weed.
I am just too genius for this board at times.

I haven't smoked in decades and my experience was always much more mellow and pleasant.
I haven't smoked weed in over 2 decades and that's the only considered illicit drug I have taken. That clip seems more in alignment with what someone may experience on something more hardcore like LSD.
Norman! What did you put in my tea?

I didn't dislike it, but it doesn't give me a vibe like any I've ever had with weed. I haven't smoked in decades and my experience was always much more mellow and pleasant. Like this:
Is your video what it's like
for you
when you're high on today's much stronger weed?

A lot of people probably won't like it. And a small number of people will like it.
It's 80s experimental animation, low-budget. I love it.
"My life is over. I might as well dance with Johnny Slash!"

Do we have to look at it?

That "visual" is hectic af.
